Electricity is a common product in our life, because its appearance greatly facilitates our life. In order to make electrical appliances work properly, we need the help of wires, which are the most common items in our life. Wire is an important equipment for power transmission. In the development of wires, we have a variety of wire equipment, and the upgrading and replacement of wires are also very fast. Copper clad aluminium wire is a kind of common wire. It is of great use. Let's introduce how to distinguish the quality of copper clad aluminium wire.
Copper-clad aluminium wire refers to the wire with aluminium core as the main body and a certain proportion of copper coating on the outer surface. The main function of this kind of wire is to transmit signals. It can be used as conductor of coaxial cable and conductor of wire and cable in electrical equipment such as household audio connector. However, because the conductivity of aluminium is only two-thirds of that of copper, once used, the temperature of the conductor will rise, which brings about some potential safety hazards and is even more dangerous for underground and closed projects. Therefore, the national standards stipulate that all wires and cables used to transmit electricity need to use annealed copper wires without metal or metal as conductors, and prohibit aluminum wires, including copper-clad aluminum wires, as conductors. As a conductor material, aluminium has many advantages, but it also has its inherent disadvantages: easy oxidation, high contact resistance, can not be welded with solder, and is more corrosive than copper, resulting in copper being replaced by aluminium.
Several methods for identifying the quality of copper clad aluminium wire are briefly introduced. I believe that after reading the above, everyone will have their own unique understanding, because a single material conductor does have many shortcomings, these shortcomings can be well avoided by this combination or alloy material conductor. It combines the advantages of these two materials. If necessary, we can choose our copper clad aluminium manufacturer for purchase and consultation.
